Conceptual Design of A Pilot’s Decision-Making Support System for Tactical Separation of Small Air Transport Vehicles in Future Sesar ATM Environment

摘要

This paper provides the conceptual description of the Tactical Separation System (TSS) which design is ongoing in the EU funded project COAST (Cost Optimized Avionics System), under the Clean Sky 2 research and development programme. The TSS is an ADS-B-based advanced self-separation system aimed to extend the traffic situational awareness and to provide the pilot with suggested manoeuvres aimed to maintain the required separation minima. It constitutes not only an enabler for single-pilot operations in SAT vehicles and for the implementation of the separation responsibility delegation to the flight segment in the future SESAR environment, but it also constitutes a step-forward in the framework of the development of Airborne Separation Assurance Systems (ASAS) for Small Aircraft. The TSS receives consolidated traffic picture (position and velocity of all tracks) from the ADS-B receiver and its own position and velocity from the GNSS receiver, all consolidated by dedicated traffic data processing application. Based on this overall information, the TSS perform its main assigned functions, i.e. Conflict Detection and Conflict Resolution. In the paper, a description is first reported of the overall TSS architecture and of its concept of operations. Based on that, an overview of each functionality implemented in the TSS is reported, namely with reference to: Coarse Filtering, Conflict Detection, Severity Assignment, Conflict Resolution and overall TSS Logic. Finally, the design process that is ongoing is outlined and the future developments are indicated.
